<\/div>\nZipArchiver Class<\/h2>\n
The ZipArchiver is a custom PHP class that helps to create a ZIP file from folder (files and sub-directories) on the server using the ZIP extension<\/b>.<\/p>\n\n- zipDir()<\/b> – This function creates a Zip of a folder recursively including the parent directory.\n
\n$sourcePath<\/code> – Relative path of the directory to be zipped.<\/li>\n$outZipPath<\/code> – Path to save the zip file.<\/li>\n<\/ul>\n<\/li>\n- dirToZip()<\/b> – It is a helper function of ZipArchiver class that adds files and sub-directories in a folder to the zip file.<\/li>\n<\/ul>\n
